People are asking if you can make larger loaves, and the answer is a definite yes. Here you see a batch of dough made into two larger baguettes, which took about 20 minutes to bake, I think. I should have timed it for you, but I was mesmerized by their beauty as I kept peeking to see if they were done, and never checked the clock. It's hardly my fault.
You can also make one giant loaf, but may want to reduce the temperature to 450 F., since the baking time is going to be longer, maybe 35-40 minutes or so. By the way, you can always test with a thermometer, and pull the bread at an internal temperature of 190-200 F. Enjoy!
